PUMP.

SPECIFICATION forming part of Letters Patent No. 268,845, dated December 12, 1882.

Application filed April 29, 1882. (No model.)

To all whom it may concern Be it known that I, BENJAMIN O. VANDU- ZEN, of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

The object of myinvention is to simplify the construction of pumps without rendering them less efficient in operation; and it relates more particularly to that class of pumps which are suspended in the well, and in which the pumping-cylinderis located at onesideof the pumpstock.

The principal feature of my invention relates to such a construction and arrangement of parts as will permit of a ready removalof the pumping-cylinder, together with the various valves, for the purposes of repairing or replacing any of such parts.

The various other features of my invention wiil'be apparent from the following description and the drawings, in which- Figure 1 represents an elevation of my invention, partly in section, showing one form of joint connecting the various parts. Fig. 2

represents a transverse section of the pumping-cylinder and vacuum-chamber, taken at the line a w of Fig. 1,showing the construction and arrangement of the lower valve. Fig. 3 o'is a side elevation of the upper part of the pump. Fig. 4 is a central longitudinal section through the pumping-cylinder, vacuum-chamber, and discharge-pipe, showing the preferred construction of the joints between the various 5 parts.-

A is the body or support of the pump, and.

consisting ofthe base a and the hollow pillar a,thetwo beingconnected byasuitable brace, as a. Through this pillar a passes the diso charge-pipe B, which is prevented from movinglongitudinally therein by the keys b, which enter apertures in the pillar a, made for their reception, and when the keys are driven into position they impinge'against the pipe B, pre- 5 venting any longitudinal movement.

On the top end ofthe discharge-pipe B is screwed the head or top B, which is provided with a spout, b, and the brackets b between which the handle 0 is pivoted.

of which maybe provided with a circularshoe flare in the end of the casting G, as shown in If desired, an ornamental casing, G,may be placed around'the discharge-pipe 13, between the pillar a and the top B.

To the lower end of the discharge-pipe B is screwed the casting D, in which is formed the vacuum'chamber d, a partition, d, preventing any communication between the upper end of said chamber and the discharge-pipe B. The lower part of this casting D is provided with a curved tubular projection, D, the upper end or seat, E,or preferably,'as is shown in Fig. 4, with a circular head, D The upper end of the casting D, above the partition d, is provided with a curved lateral passage, E.

In the lower endot' the casting D is screwed the suction-pipe F, which extends down into the well to the required distance.

' The pumping-cylinder is formed in the casting G, and consists of the chambers gg, in which operate the pistons h h, which are connected to the pump-rod H, which latter is con-- nected' to the pump-handle O by the bolt 1. The casting G is provided with a curved tubular projection or passage, G. When the castings D and G are in position with relation to each other the lower end of the casting G, being slightly flared, fits-around the circular head D on the projection D of the casting D, the head being beveled to correspond with the Fig. 4. The end of the opening or passage through the projection G is also flared, as shown in Fig.4, and into this flared opening fits the head ofthe projection E on the casting D. Both of these joints are rendered watertight by means of elastic rings or gaskets j,

which fit into channels or grooves around the heads of the projections which fit into the flared openings, thus preventing the packing from being displaced. When the castings D and G are connected and constructed as above described they occupy the position shown in Fig. 4:. If preferred, however, the construction and arrangement shown in Fig. 1 may be employed. In this figure the projection D of 9 the casting D is provided with a circular shoe or seat, E, into which the end of the casting G fits, and the end of the projection G fits into the mouth or opening of the passage E, elastic packing being interposed in each instance, as in the first-described construction. While the construction shown in Fig. 1 may be advantageously employed, I prefer the construction shown in Fig. 4, for the following reasons, viz: The inner surface of the cylinders gg is bored out smooth and usually enameled, and by forming the lower end of the casting G as shown in Fig. 1 the fiaringlower end of casting may easily be enameled, or otherwise made smooth, and thus a tighter joint can be made than by the construction shown in Fig. 1.

The casting D, when formed as shown in Fig.4, is more easily cast than when ofthe form shown in Fig. 1, as the shoe E makes a difficult point to draw from the sand. When formed as shown in Fig. 4 the valve-seat on the end of the projection D is more easily made smooth and even than when the casting is of the form shown in Fig. 1. The elastic packings j are not so liable to be disarranged when the castings are of the form shown in Fig. 4 as when of the form shown in Fig. 1, as in the former case they remain with the casting D left in the well, and are not disturbed, while in the latter case they are lifted from the well with the casting G, and are liable to be interfered with.

One end of a rod or tube, J, is screwed into the projection G and extends upward nearly to the bracket or projection 70, projecting from one side of the pillar a. Through this projection passes a set-bolt, K, which is screwed through said projection and rests in a depression in the end of the pipe or tube J, which latter is preferably made in the form of a tube, the interior of which communicates with the interior of the passage G, as shown, in which event it serves the double purpose of an airchamber and as a rod for keeping the various parts of the pump in position.

In very deep wells, where the pumping-cylinders are located a considerable distance below the surface of the ground, it will be found desirable to place the bracket or projection is lower downas, for instance, at some point below the ground-connectin g it to the pipe B, so that the distance between said bracket and the projection G shall not be great.

In the lower end of the pumping-chamber g is placed the drop-valve L, which, when thecasting G is in position, rests on the upper end of the tubular projection D, which forms a valve-seat for said valve. The hinge of this valve is connected to a lug, l, projecting inwardly from an open ring, M, which latter is placed loosely in the end of the chamber g, but is held therein by its own inherent elasticity. One or two other projections, an, extend inwardly from the ring M, and the valve L is provided at points immediately over these projections with small lugs or Wings 11. By this construction, when the casting G is lifted the wings n on the valve will be above the projections m, and the valvewill thus be prevented from dropping down. j

I Thewater is drawn up from the well through the suction-pipe F, the vacuum-chamber d causing a more steady suction, and into the chamber 9, from whence it passes through the piston h, a portion entering the chamber 9, and a portion passing out through passages G and E into the discharge-pipe B and out through the spout b. As the water passes through thepassage G a portion of it enters the pipe J, which, being closed at its upper end, acts as an air-chamber, which causes a steady flow of water from the discharge-pipe.

By the construction above described the pumping-cylinders and pistons and valves may be very easily lifted from the well, the only bolts necessary to be removed being the set bolt K and the bolt I, connecting the pumprod H to the handle 0. When these bolts are removed thecastingG,containingthepumpingcylinders and the various pistons and valves, may, by means of the pump-rod H and rod or pipe J, be lifted, the projection G beinglifted from the projection E and the lower end of the casting G from the projection D, and when the casting G is to be replaced in the well, to the position shown in the drawings, it is very easily accomplished, and when in this position is firmly held there by the set-bolt K, the gaskets or packing j preventing any leakage between the pumping-cylinders and the casting D.

Having thus described my invention, what I claim as new and of my invention, and desire to secure by Letters Patent, is as follows:

1. In a pump, the combination of a cylinder provided with a flaring mouth or end, and the cylinder-head or valve-seat beveled to fit said flare, and an annular packing interposed between said flaring mouth and the head, substantially as and for the purposes specified.
